In the current research, effect of milling on the structure, particle size and morphology of montmorillonite was investigated. For this purpose, the montmorillonite was analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). Then the montmorillonite was milled using high energy planetary ball mill at different milling times (1...

Domestication of animals has had some important effects on physiology, morphology, behavior and well-being of domesticated animals. Conscious or goal directed selections on animals for increasing their productions has accelerated the rate of the changes, leading to some well-being defections. This paper notes some aspects of animal domestication in context of genetic science. Then explains how ...

Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size an...

Background: It is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. In the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. Materials and Methods: In this study 60 units of packed red cells were examined before and after p...

  Background: Intervertebral disc herniation has two common types, extrusion and protrusion, which may affect the adjacent vertebrae.In addition, it is associated with significant signal changes in T1 MRI (short TR/TE) and T2 MRI (long TR/TE).   Methods: The present study is a cross-sectional analytic one, in which sampling was performed retrospectively. Cases were randomly selected from the pa...

In this study, melt-spun Finemet ribbons were coated by a thin layer of SiO2 using dip coating method. Amorphous ribbon prepared by melt spinning method and dip coating were done by using a solution of tetraethylen orthosilicate as a SiO2 precursor, ethanol as solvent and distilled water for hydrolysis. Different thicknesses of SiO2 layer, namely 304, 349, 451, 526 and 970 nm were obtained prop...

BACKGROUND/PURPOSE Does the morphology of wrinkles alter gradually with aging or suddenly at a certain age? On the basis of the theoretic wrinkle simulation of ideal skin, we have suggested that the wrinkle morphology suddenly changes from stratum corneum wrinkling to epidermis wrinkling; the former induces shallow fine furrows, and the latter induces deep prominent wrinkles. To examine the exi...

The morphology and physiology of both the vulva and vagina undergo characteristic age-related changes over a lifetime. At birth, these tissues exhibit the effects of residual maternal estrogens. During puberty, the vulva and vagina mature under the influence of adrenal and gonadal steroid hormones. During the reproductive years, the vagina responds to ovarian steroid hormone cycling, and both t...
